As a business analyst or business rules developer, you can use test scenarios in Business Central to test a decision service before a project is deployed. You can test DMN-based and rules-based decision services to ensure these are functioning properly and as expected. Also, you can test a decision service at any time during project development.
- The space and project for the decision service have been created in Business Central. For details, see Getting started with decision services.
- Business rules and their associated data objects have been defined for the rules-based decision service. For details, see Designing a decision service using guided decision tables.
- DMN decision logic and its associated custom data types have been defined for the DMN-based decision service. For details, see Designing a decision service using DMN models.
Having defined business rules is not a technical prerequisite for test scenarios, because the scenarios can test the defined data that constitutes the business rules. However, creating the rules first is helpful so that you can also test entire rules in test scenarios and so that the scenarios more closely match the intended decision service. For DMN-based test scenarios ensure that the DMN decision logic and its associated custom data types are defined for the decision service.
